Diane was walking back at a steady pace towards the fifth floor with her backpack still slowing her down (not that she made a lot of effort), with Anna possibly coming behind her. She looked around and saw nobody. She peeked into the lab, and saw no immaterial person. She hummed pensively and returned to the corridors in front of the lab door. "Maybe we should go to the owlery to contact the others," she said out loud but, more to herself than anything. They had roughly been an hour out. It was difficult to tell if that was too long or too little.
